SEWING MACHINE ATTACHMENT Filed June 15, 1928 Patentcdda. 2,7, 1931 .A1-BERT LITTLE, 0l' BOSTON, MASSACHUSETTS smc-mem Arracmmmrr application med :une 15, 192s. serial 110,285,563.

This invention relates to sewing machine attachments and pertains more particularly to that class of attachments used for guldmg the material to be stitched by the needle of 5 the sewing machine. rlhe principal object of the invention is to provide a pair of cooperating guide members of simple and economical construction adapted properly to position with certainty a piece oi base material and two other pieces of fabric as they approach the stitching needle to be served with the edge of thb base fabric lying between the margins of the other pieces.

The sub'ectI matter of the invention has especial utllity when .employed to guide the strips of fabric constituting after stitching the waist band of a garment such as mens y trousers, in which a composite strengthening bend comprisinga finished lining and a canvas reinforcement is to be sewed to a strip of material of the same character as the garment.- The invention will accordingly be illnstrated and described in connection with materials of this nature, and further objects, residing in the construction and arrangement of the attachments, will be apparent from the following description and will be pointed out in the appended claims.

A recommended embodiment of the invention is 'illustrated in the accompanying dra.W- ings,.in which:

Fig. 1 is a plan view of a portion of a sewing machine equipped with the improved guides;

Fig. 2 is an enlarged section on the hne 2-2 of Fig. 1 illustrating the arrangement of the guides and the positions of thefabric strips; and

Fig. 3 is a fragmentary section taken on the line 3-3 of Fig. 2'.

The attachments comprise essentially a pair of cooperating guide members 4 and 5 preferably adjustably mounted with respect to each other upon the bed 6 of a sewing machine and in suitable proximity to the needle 7 carried in the needle bar 8. To permit adjustment of the guides toward and from each other, the guide plate 4 has a pair of transverse slots 9 receiving screws 10 and the guide member' carries a mounting bracket 11 havin slots 12 receiving screws 13.

he guide plate 4 preferably consists of a metal sheet having an upstanding flange 14 along its inner side, the plate being bent upwardly of the bed 6 along a line 15 parallel to said ange to provide a raised gulde surface dening Van underlying longitudinal cloth recess 16. The upper edge of the flange 14 is preferably inclined downwardly toward tre nedle end of the plate as indicated at 17,

The other guide member 5 consists of a metal sheet in the form of a substantially dat sided sleeve inclined downwardly on its bracket 11 toward the needle 8 at substantially the same angle 'as the flange edge 17. The sleeve comprises a top part 18, an underlying portion 19 returned from the inner longitudinal folded edge 20 of the sleeve, and a bottom flap 21 folded inwardly as at 22 from the opposite longitudinal edge of the sleeve.

The underlying portion 19 serves as a fabric support and guide and extends outwardly so as to be disposed parallel to the top 18 with itsouter edge 23 spaced a short distance from the fold 22. Similarly the flap 21 is disposed in spaced parallel relationship to the outer margin of the support 19.

- The two guide members are so arranged l,

with respect to each other that the inner fold 20 of the sleeve ide 5 overlaps the inner flanged margin o the guide plate 4, whereby the margins of the materials guided by the folded sleeve and the plate respectively will be fed toward the needle 7 for correct stitching. It will be observed from the foregoing and from the subsequent description of the arrangement of the fabrics to be stitched that the width of the multiply hem will be governed by the extent of the overlap of theY guide members, and that said overlap may' be adjusted by the screws 10 and 13.

As illustrated in Fig. 2, the materials to be guided by the attachment and stitched by the needle may include a strip of base material 24 which rests upon the guide plate 4 with its inner edge abutting and guided by the flange 14; a strip of lining material 25 fitting within and guided by the sleeve 5' ping and with the edge of the third of sewing machine,

and preferably having an unstitched hem 26 along its inner edge abutting the fold 20; and a canvas reinforce 27 having its outer edge sewed to the lining as at 28 and having its inner margin received within the recess 16 and guided by the raised platform of the plate 4.

WhenV the materials thus arranged and guided are fed toward the needle, it will be apparent that their overlapping margins will be correctly sewed together by any suitable stitch performed by the needle and that in the resulting multiply hem the edge of the base material will be interposed between the margins of the hemmed lining and the canvas reinforce respectively. In the finished waistband the base material is folded and pressed over the canvas reinforce so that the edge thus formed is smooth and secure and not excessively thick. It will be particularly observed that the edge of the canvas'is not folded but that its rough edge serves as a sharp fold line for the base material and a" iirm edge at the top of the waistband. The product roduced by the operations herein set forth 1s more fully described and claimed in my copending application Serial No. 285,562 filed June l5, 1928.

p The attachments embodying the present invention are simple and economical to manufacture, easily applied to any ordinary type and readily adjusted to produce stitched seams of the desired width. The guides permit easy feeding of the material to the needle and properly and eii`ectively position the three strips of material as they move toward the needle. Details of structure may be varied to suit articular purposes without departing from t e essence of the invention as defined in the following I claim:

l. Devices adapted to be attached to sewing machines to guide three stri s of material to the needle to be stitche together, comprising a sleeve for positioning one of the strips and the body portion of the second strip, and a guide plate having anu standing flange at its inner edge for guidlng the edge of the third strip and having a channel for guiding the inner edge of said second strip, whereby the three strips are fed to the needle with their inner edges overlapstrip between the margins of the other two strips.

2. Devices adapted to be attached to sewi ing machines to guide three strips of material to the needle to be stitche together, comprismg a sleeve provided with a downwardly linclined guideway for one of they strips, and a guide plate having an upstanding iange along its inner edge disposed beneath the inner margin of said guideway and having a guide channel disposed beneath said iianged edge, said channel being adapted to receive and position the inner edge of a second strip of material which is connected alon its opposite edge to the outer ed of the rst-named Ystrip and said flan e ing adapted to guide the inner edge o a third strip slideable on said guide plate, whereby the three strips are fed to the needle with their inner edges overlapping and with the edge of the third strip interposed between the margins ofthe other two strips.
